量温检测技术在采空区内因火灾预报中的应用

采煤工作面采空区不可避免地要有可燃煤的存在,采空区漏风流场供氧条件下,自燃破碎的煤极易形成内因火灾,严重影响着矿井的安全生产。采用温度观测法辅助预报手段,可以及时掌控采空区内部状况及采空区内煤体氧化规律,提供自然发火防治措施的决策依据,从而保障矿井的安全生产,具有巨大的经济、安全和社会效益。

Application of Temperature Detection Technology in Gob Breeding Fire Prediction

It is inevitable to exist the combustible coal in the coal face gob.Under the oxygen conditions of gob leakage flow field,it is easy for the combustible and broken coal to form breeding fire,with a serious impact on mine safety in production.Taking the auxiliary temperature observation as a prediction method,the gob internal situation and gob coal oxidation can be grasped.The dicision-making basis is provided for prevention of spontaneous combustion in order to protect the safety of mine production,with hug...
